What’s wrong with this problem?

```julia
julia> using Pkg

julia> Pkg.update()
    Updating registry at `~/.julia/registries/General.toml`
┌ Warning: could not download https://pkg.julialang.org/registries

If you’re in mainland China, you can target to the mirror servers

For instance, downloading from BFSU server would be blazingly fast by setting the environment variable:

```julia
julia> ENV["JULIA_PKG_SERVER"] = "https://mirrors.bfsu.edu.cn/julia"

```
